Kevin,
sorry you've found yourself here, but you will get excellent support.
You are at the most anxious stage - it's all new to you, wasn't expected, no idea what will happen but you've heard bad stuff and almost certainly imaged even more. We've all been there and we all know how anxious a time it is, and we're feeling for you. You need to work through the next few weeks of diagnostic procedures to find out if there's any issue. You haven't been diagnosed with prostate cancer yet, and we all hope you won't be.
What can you expect next?
It's not clear if you've been referred to follow a prostate cancer diagnostic path or some other diagnostic path. For the prostate cancer one, you would likely have an MRI scan (multi-parametric MRI scan) and maybe a few things like a digital rectal exam, and some flow tests (peeing into a flow rate machine). They will then wait for the scan result, and decide if they need to do a biopsy or not.
You didn't say where the ct scan anomalies are, and it may be that they will be following a different diagnostic path than prostate cancer.
Please feel free to ask absolutely anything here. It's also useful if you can give test results and dates for things like PSA in your profile. This helps people tailor answers more specifically to your circumstances.
